Using Bugzilla might be little complicated for few due to grouping users and granting permission | For some using JIRA would be more convenient than Bugzilla |
Bugzilla ALLOWS you to show/hide the whole custom field or specific values based on the value of some other field | JIRA ENABLES conditional configuration based only on Type fields and Project |
Bugzilla’s has a powerful advanced search option | JIRA LACKS advance-level search options. JIRA has flexible JQL language (JIRA uery Language). It enables you to build arbitrary Boolean expressions. |
Unlike JIRA, Bugzilla allows users select the initial status of a new issue. | Unlike Bugzilla, JIRA enables you to define multiple workflows which are applied based on the issue’s Project and Type. |
Bugzilla has only one link type: Blocks/depends and a Bug ID custom field | JIRA has configurable link types with user DEFINED semantics. JIRA enables to link an issue to any other entity OUTSIDE JIRA. |
